Development of a hagfish skin gelatin film containing cinnamon bark essential oil

Kim, Hyeri,Beak, Song-Ee,Song, Kyung Bin Elsevier 2018 LWT- Food science and technology Vol.96 No.-

<P><B>Abstract</B></P> <P>Hagfish skin, which is discarded before cooking the fish, can be used as a source of gelatin. In this study, hagfish skin gelatin (HSG) films containing cinnamon-bark essential oil (CBO) were developed as an active packaging material. The SDS-PAGE profile of HSG revealed bands of α and β chains at 130 and 250 kDa, respectively. The HSG films had 30.5 MPa of tensile strength (TS) and 9.18% of elongation at break (E). The addition of 1% CBO to the HSG films resulted in a decrease in the TS and an increase in the E. In addition, the contact angle of the HSG films were changed from 70.9 to 90.5° with the addition of CBO from 0 to 1%. In particular, the HSG films containing 1% CBO had antibacterial and antioxidant activities as well as suitable physical and water barrier properties. Therefore, HSG films containing 1% CBO can be used as food packaging materials to maintain the quality of foods by reducing the risk of microbial spoilage and lipid oxidation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Hagfish skin gelatin (HSG) was used to prepare biodegradable films. </LI> <LI> Cinnamon-bark essential oil (CBO) was added as a natural active material. </LI> <LI> HSG films containing CBO had good antibacterial and antioxidant activities. </LI> <LI> Water resistance of the HSG films was enhanced with the addition of 1% CBO. </LI> <LI> HSG films containing CBO can be used as food packaging materials. </LI> </UL> </P>

Characterization of <i>Ecklonia cava</i> Alginate Films Containing Cinnamon Essential Oils

Baek, Su-Kyoung,Kim, Sujin,Song, Kyung Bin MDPI 2018 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.19 No.11

<P>In this study, <I>Ecklonia cava</I> alginate (ECA) was used as a base material for biodegradable films. Calcium chloride (CaCl<SUB>2</SUB>) was used as a cross-linking agent, and various concentrations (0%, 0.4%, 0.7%, and 1.0%) of cinnamon leaf oil (CLO) or cinnamon bark oil (CBO) were incorporated to prepare active films. The ECA film containing 3% CaCl<SUB>2</SUB> had a tensile strength (TS) of 17.82 MPa and an elongation at break (E) of 10.36%, which were higher than those of the film without CaCl<SUB>2</SUB>. As the content of essential oils (EOs) increased, TS decreased and E increased. Addition of CLO or CBO also provided antioxidant and antimicrobial activities to the ECA films. The antioxidant activity of the ECA film with CBO was higher than that of the film containing CLO. In particular, the scavenging activities of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals in the ECA film containing 1% CBO were 50.45% and 99.37%, respectively. In contrast, the antimicrobial activities against <I>Escherichia coli</I> O157:H7, <I>Salmonella</I> Typhimurium, <I>Staphylococcus aureus</I>, and <I>Listeria monocytogenes</I> were superior in the ECA films with CLO. These results suggest that ECA films containing CLO or CBO can be applied as new active packaging materials.</P>

메타중아황산나트륨을 다공성물질에 함침하여 제조한 비금속류 산소제거제의 산소제거속도 향상 및 식품 포장 적용 연구

정수연,이현규,유승란 한국포장학회 2024 한국포장학회지 Vol.30 No.1

The addition of oxygen scavengers to food products helps to reduce oxygen exposure, thereby mitigating deterioration, including changes in taste, odor, and color, as well as inhibiting microbial growth. Despite the advantages of the existing non-metallic oxygen removal materials in terms of safety for the human body and suitability for use in microwave ovens, their utilization has been limited due to their slow reaction initiation speed. Therefore, in the current study, sodium metabisulfite was impregnated into various porous media, including halloysite nanoclay, activated carbon, montmorillonite, and silica gel. The oxygen scavenger, produced by impregnating silica gel with sodium metabisulfite, demonstrated a 425% improvement in the initial oxygen removal rate compared to pure sodium metabisulfite. Additionally, sachets containing an oxygen-removing composition with an enhanced oxygen removal rate effectively decreased the oxygen concentration to less than 0.5% on the third day of storage in apple packaging, without elevating carbon dioxide levels. Moreover, it proved effective in preventing the browning of the apple surface. Therefore, the SM/SG oxygen-removal composition can be effectively applied to active food packaging by controlling the oxygen concentration within the packaging.

박물관ᐧ미술관 교수ᐧ학습매체 개발과 활용 방향: 어린이 박물관ᐧ미술관을 중심으로

김해경(Hai-kyung Kim) 한국문화교육학회 2017 문화예술교육연구 Vol.12 No.1

박물관ㆍ미술관 교육에서 대부분의 학습이 교수자 없이 이루어지는 상황을 고려하면 교수ㆍ학습 매체는 박물관ㆍ미술관 교육에서 매우 중요한 위치에 있다. 따라서 본 연구에서는 현재 사용되고 있는 교수ㆍ학습 매체의 문제점을 알아보고 교수ㆍ학습 매체의 개발과 활용 방향에 대해 논의해보고자 하였다. 박물관ㆍ미술관의 교수ㆍ학습 매체가 갖고 있는 문제점으로는 학습자의 요구와 상황에 맞추어 세분화되지 않은 점, 교수ㆍ학습 매체의 종류 및 형식이 유사한 점, 어린이 박물관ㆍ미술관 내 전시물에 진품 전시가 드물다는 점, 작동이 되지 않는 전시물이 그대로 방치되는 점을 지적하였다. 이러한 박물관ㆍ미술관의 교수ㆍ학습 매체 개발과 활용 방안으로는 다양한 관람객의 상황에 맞추어 교수ㆍ학습 매체를 세분화할 것, 교재보다 교구 형태의 교수ㆍ학습 매체 개발에 더 많은 관심을 가질 것, 새로운 종류와 형식의 교수ㆍ학습 매체 개발에 관심을 가질 것, 교수ㆍ학습 매체 개발과 유지에 드는 비용 대비 효과를 고려할 것, 어린이 박물관ㆍ미술관 내에서 진품 전시를 고려할 것, 고장 및 훼손에 대비한 예산 확보와 관리 지침을 수립할 것을 제안하였다. 교수ㆍ학습 매체 활용 방안으로는 첫째, 관람객의 연령별로 관람 동선을 제시하거나 전시물의 이용 방법을 달리 안내할 것과 교구재 대여 사업을 하는 박물관ㆍ미술관의 경우 교육 전문가가 원거리 교육 지원을 통해 교구재 활용을 지원할 것을 제안하였다. Considering most learning to be happened without a instructor in museum except participating in education program, teaching-learning materials are very important in museum education. Therefore, it is needed to find out problems of currently being used teaching-learning materials in museum education and to discuss the directions of developing and applying them. The first problem of teaching-learning materials in museum education is not to meet the needs of diverse visitors. Second, the types and styles of them are similar. Third, children s museums rarely exhibit real remains or artworks. Fourth, broken exhibits are neglected without immediate repair. The directions of development of teaching-learning materials in museum education are 1) to be subdivided teaching-learning materials by visitors age, types and degrees of disability, education, etc; 2) to concern for developing hands-on type teaching-learning materials; 3) to consider substitutes for high-priced teaching-learning materials; 4) to seek for the ways to use real remains and artworks as teaching-learning materials in children s museum; 5) to secure a budget for repairing and to develop a care instructions for teaching-learning materials. Two ideas are suggested as applying teaching-learning materials in museums. First, diverse visitors paths can be developed according to visitors needs and interests, so visitors can know which exhibits are suitable for their needs and interests. And, same teaching-learning materials can be applied in different ways. For example, kindergartners can learn about the name of color with pieces of a puzzle and primary school students can put the puzzle together. So, the way to apply teaching-learning materials in diverse ways can be suggested. Second, a museum educator can co-teach with a teacher by videotelephone who are borrowed teachers package.
